The future Of biogas utilizations in China

The existing energy is almost provided by carbon-containing fossil sources such as oil and coal. The rapid consumption of these fossil resources causes an accelerated release of CO₂ which is a major cause of global warming and associated climate change. "Green" bio-methane (also named biogas) has the advantage for both reducing over dependency on fossil energy and reducing emissions o CO₂ and other greenhouse gases (GHGs). The purpose of this work is to introduce the biogas utilization ways widely applied in China and indicate the development orientation on clean, effective and economical utilizations. Firstly, biogas in china should gradually walk out from rural family, come into centralized anaerobic digestion (CAD). Secondly, combined production of heat and power (CHP) and upgrading to vehicle fuel should be popularized extensively. Thirdly, biogas fuel cell systems and biogas chemical industry (BCI) should be exploited as a technique reservation.
